Abstract: PURPOSE:To obtain the combustion safety device, which safely operates when oxygen concentration in a chamber lowers remarkably, by setting up a voltage generating sensor by the intensity of red-heat light at a position where the sensor is heated by a combustion flame or a combustion gas between an outer cylinder and a heat-resistant glass cylinder and grasping a weak temperature change as the change of light. CONSTITUTION:A combustion chamber 22 is formed in such a manner that an inner cylinder 20 and outer cylinder 21 made of a heat-resistant metal are installed concetrically onto an annular plate 6 in space surrounded by the heat-resistant glass cylinder 18 and a cover body 19. When combustion is started, the nose of the sensor 38 is heated by a flame of a burner port 24, a gas cock 13 is opened, and combustion is continued. In this case, the oxygen concentration of indoor air is normal, the nose of a sensor pipe 32 is heated by the flame from the burner port 24, luminous energy generated is much, and output voltage from a light-receiving element 36 is kept at large value. The light-receiving element is cooled by combustion air sucked from an air guide hole 17 at that time, and breakdown by heating is prevented. When indoor oxygen concentration drops, however, a range of the formation of the flame moves upward, the burner ports 23, 24 of the lower sections of the inner and outer cylinders 20, 21 are used entirely for supplying air and made the same state as there is no burner port, a temperature in the vicinity of the sensor pipe drops, luminous energy introduced to a light receptor 15 decreases, and voltage generated is reduced. The voltage is detected, a control circuit 37 flows reversely excited currents through the gas cock 13, a gas flow path is closed, and the state of  oxygen starvation is prevented previously.

Abstract: PURPOSE:To reduce bad influence by load impedance to the utmost, by separately amplifying a linear component against an input signal, and a non-linear component generated by a variation of load impedance, and supplying then to a load. CONSTITUTION:Between an output of the first amplifying circuit 10 whose voltage gain is A, and ground, a bridging circuit 11 having each branch line consisting of resistances RA, RB and RS and a load 4 (ZL) is provided, and to a bridging circuit connecting point opposed to one end of the load 4, an input of the second amplifying circuit 12 is connected, and its output is connected to the load 4.

IPC: H01L21/60
Filed: 1978-04-19
Abstract: PURPOSE: To eliminate a short circuit by forming a wire in a desirable arch shape, by automatically ajusting the curving start height of the wire of each junction distance.  
     CONSTITUTION: At the time of a wire connection between two points, a tacho- generator is attached to a Z motor controlling the vertical movement of a capillary, and the output is integrated into a saw-tooth waveform; the waveform becomes the highest in voltage from the rise of a holding tool to the end of a one-cycle connection and is cleared at each cycle. On the other hand, the distance between two points to be connected is extracted as bit information by the X-Y movement distance register and the information is used as the address to read out PROM information. The read information is D/A-converted to compares voltage at respective points of saw-tooth wave 4 and a plane movement start signal is generated at the point in time of coincidence, so that the movement will start. As the connection interval is longer, the originating time is later. Therefore, adequate wire connection can be made at the fabrication of various devices only by changing PROMs, so that wire shorting can be prevented.
